Ezikhathini zamuva, izinto eziningi ezintsha ziye zavela, ukuze izinto ezinezindleko eziphakeme esikhathini esidlule ziye zashintsha kancane kancane ngentengo, ikakhulukazi ezicathulweni namapayipi.
?
Yiqiniso, ezinye izinto zibonakala zisesimweni esihle. Ngemva kophenyo, ungakwazi ukuqonda ukuthi yiziphi ezinye izici.
?
Isibonelo, izinto ezimbili ze-pvc ne-pu, abantu abaningi bebelokhu benokungabaza, ngakho-ke umehluko phakathi kwezinto ze-pvc ne-pu?
?
Umehluko phakathi kwezinto ze-pvc ne-pu
?
Isikhumba se-PU siyinkimbinkimbi kakhulu kunesikhumba se-PVC ekukhiqizeni inqubo. Ngoba indwangu yesisekelo se-PU iyindwangu ye-PU ye-canvas enamandla aqinile, ngaphezu kokumbozwa kwendwangu ephezulu, indwangu yesisekelo nayo ingafakwa phakathi ukuze iyenze Ukubukeka akukwazi ukubona ubukhona bendwangu.
?
1. Izinto ezibonakalayo zesikhumba se-PU zingcono kunesikhumba se-PVC, zimelana ne-tortuosity, ukuthamba, amandla aqinile aphezulu, futhi ziphefumula (ayikho i-PVC).
?
Iphethini yesikhumba se-PVC yakhiwa ngokucindezela okushisayo kwama-roller ephethini ensimbi. Iphethini yesikhumba se-PU iyashisa icindezelwe ebusweni besikhumba esiqediwe kancane ngohlobo lwephepha lephethini. Ngemuva kokulinda ukupholisa, isikhumba sephepha siyahlukaniswa futhi siphathwe phezulu.
?
Intengo ye-PU ingaphezu kokuphindwe kabili kwe-PVC, futhi intengo yesikhumba se-PU enezidingo ezithile ezikhethekile iphakeme ngokuphindwe izikhathi ezingu-2-3 kunaleyo yesikhumba se-PVC.
?
Ngokuvamile, iphepha lephethini elidingekayo lesikhumba se-PU lingalahlwa kuphela ngemva kwezikhathi ezingu-4-5. Isikhathi sokusebenzisa i-roller yephethini side, ngakho-ke izindleko zesikhumba se-PU ziphakeme kunezesikhumba se-PVC.
?
2. Indlela yokuhlukanisa i-PU ne-PVC ilula kakhulu.
?
Kusuka emakhoneni, isisekelo sendwangu ye-PU sikhulu kakhulu kune-PVC. Kukhona nomehluko emuzweni. Umuzwa we-PU uthambile. I-PVC izwakala ilukhuni.
?
Ungasebenzisa futhi umlilo ukushisa, ukunambitheka kwe-PU kulula kakhulu kune-PVC.
